You'd have to think twice if you wanted to make a research paper on the Holocaust, and your English professor was from Germany, because you'd have to be very careful with the things you'd put down: like that with the Nazi's, Hitler's insane views, the Jews, et cetera, amirite?

I mean, as long as you're not saying shit like "ALL GERMANS ARE EVIL NAZIS" I don't think there's really much you have to walk on eggshells about.

In this day and age, your professor may not have even been born to see the Hitler's reign, let alone be old enough to understand it or form an opinion.
